We present a genome assembly from a female specimen of Zerynthia rumina (Spanish Festoon; Arthropoda; Insecta; Lepidoptera; Papilionidae). The assembly contains two haplotypes with total lengths of 852.84 megabases and 775.60 megabases. Most of haplotype 1 (99.64%) is scaffolded into 31 chromosomal pseudomolecules, including the W and Z sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.26 kilobases. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths.
